EDWARD MILLER, on MALTA, MONTANA.

SLAT FOB, BINDER APRONS.

Application filed June 5,

To all whom it may concern:

Be it known that I, EDWARD MILLER, a citizen of the United States, residing at Malta, in the county of Phillips and State of Montana, have invented certain new and useful Improvements in Slats for Binder Aprons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to that straw or weeds will be prevented from passing under the slat, tending to loosen the latter.

A still further object is to provide a device of the type indicated which may be formed of sheet metal, the sidewalls of the slat being deflected inwardly to form a channel member through which a rod passes, the canvas being looped in the channel element, and retained therein by the rod.

A still further object is to provide a grooved element formed within the bod thereof and integrally with the walls of the slat, the groove having communication with a longitudinal slot through which the looped portion of the canvas passes, the looped portion being engaged and retained by a rod received by the grooved portion and retained therein by frictional contact.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the accompanying drawing:

Figure 1 is a perspective view of the device in operative position and as applied to a section of the apron of a grain binder.

Figure 2 is a view in transverse section, on an enlarged scale, a portion of the belt or apron being shown.

Figure 3 is a perspective view of the slat, partly broken away.

Figure 4 is a view of the key rod, detached.

A section of the apron or belt is shown at Specification of Letters Patent.

16 and 17, and portions 16 and 17 extending at an angle with the elements 16 and 17. A channel member 18 is formed by deflecting inwardly, in the manner shown, the elements 1G, l6, l7 and 17, so that an approximately cylindrical tubular element is provided for receiving the looped portion of the apron. A slot 20 communicates with the channel member 18 andthe canvas passes through this slot'in loop form.

The key rod 14 is received within the loop portion of the apron or belt'and within the channel member; and the elements being of the proportions shown, a positive lock is pro vided.

One end of the rod 14 carries a head 22 which engages the adjacent end of the channel member when the elements are assembled, this head being provided with a rounded surface.

An important feature of the construction or clasp as shown in cross section in Figure 2. The walls of elements 25 and the channel member first referred to are approximately concentric. The slat per se is formed of a continuous sheet of metal, the seam being along the line 26, the elements 25 being sep- Having thus described the invention, what I claim is:

1. In a device of the class described, a grooved member formed of sheet metal and comprising outer walls and a channel member extending longitudinally between said walls and formed integrally therewith, a reinforcing device for the channel member, and'a key rod extending through said channel member for retaining a flexibleelement therein.

2. A device of the class described comprising a hollow element formed of sheet metal and having outer walls and an inner channel formed continuously with the outer walls, a slot being provided for passing a sheet of flexible material into the inner channel, an arcuate sleeve enclosing said inner channel and extending of, constituting a reinforcing device, and a prising an element substantially rectangular 1n cross section, including outer Walls, said wvalls being deflected inwardly to form a channel member Within the body of the rectangular structure a longitudinally extending reinforcing device for said channel membeig a key rod extending through the channel member adapted to retain a looped portion of a flexible element Within the channel, and a head on said rod to abut the adjacent end of the channel member.

4. A device of the class described comprising a channel member with an insert opening to receive a flexible loop, a key insertible into said channel member to pass through the loop and portions extending from opposite edges of the channel member and engaging each other to reinforce the channel memher.

In testimony whereof I afiix my signature in presence of two Witnesses.
